Hello,
Just experimenting with running the Mini from LiPo connected to BAT pads. It sort of worked at first but now I don't have any LEDs lighting at all
Is there any test points I can check or do you think that I have burned out the AXP209 ?
Thanks,
Robert

I think there is no protection circuit. Switching polarity can kill the chip

I was reading at least about one such case on Cubieboard forums. I guess this part must be wired exactly the same as on Cubietruck.

Hi Steven, So only a 3.7v battery is safe to use?

Yes, the PMU chip can manage single cell 3.7v LiPos, Looks after charging them as well.

On the back of the Mini there are 2 sets of pads where you can connect the cells.
